    Michelle Holbein-President

    My name is Michelle Holbein and I’m so excited to serve as PTO President! My daughter, Baylee, is going into 3rd grade this year and we have been at Jacobson since the spring of 2017. We relocated from Omaha, NE, which is where my husband is originally from. We were welcomed by the Jacobson staff and felt like family immediately! Brendan and I have been married for ten years and we love to travel, exercise, watch movies, and go on family outings. Prior to becoming a mom I was in sales and marketing, specifically in the medical field. However, being a stay-at-home Mom has been my favorite job ever! I also work in Women’s Ministry at our church, Compass Christian, where I enjoy organizing groups for moms and women in all stages of life. I’m looking forward to a fun filled year working with this awesome board of women to create community and enrich the culture of our school!

    I am Valentina and I am very happy to start this my first year as Jacobson PTO Executive Board Vice President. I have two children: Elisa who starts 7th grade at Bogle Junior High and Marco who starts 4th grade in the CAT'S program. We are Italian but we moved here from England, where we lived for 6 years, in December 2017. With my husband and I along with my children, like traveling and hiking. I started at Jacobson Elementary as a volunteer twice a week but I wanted to be more.

Over the last three years I have loved being a part of the Art Masterpiece Program, Space Explorers Program and classroom volunteer. My husband, Keven, is also an active member of the Jacobson Dad’s Club. I am originally from Georgia, so my accent might pop out from time to time.
